[Updated] Australia Updates Listed Medicine Ingredients, Affecting Health Supplements

Editor's Note: This article tracks the updates on Therapeutic Goods (Permissible Ingredients) Determination in 2024.

In Australia, vitamin and herbal supplements are regulated as complementary medicines by the TGA. Most complementary medicines are included in the Australian Register of Therapeutic Goods (ARTG) as listed medicines. Those medicines may only contain ingredients from an approved list of ingredients whose quality, safety and suitability for use in such medicines have been evaluated. The approved list of ingredients can be found in the Therapeutic Goods (Permissible Ingredients) Determination.
